I'm looking at an '03 blazer zr2 is 179000 to many miles or are the able to run more miles than that

 

Really depends on how those miles racked up and how maintenance was performed over those miles. I've got a 2000 ZR2 closing in on 260K miles but I've owned since new.

 

Had a 89 c/k work truck at my industrial job that had 375K on the original motor before they retired the truck.

 

They are mainly highway and the guy who's selling it is only the second owner and the first was his parents who bought it
For him but when he turned 18 they signed it over to him but it was maintained well as his father was a mechanic who cares a lot about cars

 

ive seen some cars/trucks that had under 100k on them there were just steaming piles of you know what. and other cars with tons of miles that look like new, there was a 04 accord in here yesterday with 220k and the car looked like brand new underneath, no rust and no leaks, very strange for the midwest.

my 93 s10 i bought about 8 years ago with 205k on it. best dang running vehicle i ever had
